Description

Technical Field

[0001] The present invention relates to the technical field of sampling devices, in particular to a crystallization kettle material sampling device and process. Background Art

[0002] In the chemical, pharmaceutical and food industries, crystallization kettles are commonly used equipment for separating and purifying materials through a crystallization process. During the crystallization process, sampling of materials is a key step in ensuring product quality and process control. However, existing crystallization kettle sampling devices have many problems. Traditional sampling methods usually rely on manual operation, which is not only inefficient but also prone to human errors, resulting in inaccurate sampling results. In addition, since crystals easily adhere to the inner wall of the reactor, existing devices are difficult to scrape the crystals on the inner wall comprehensively and evenly, resulting in a lack of representativeness in the sampling. In addition, cross-contamination is easily generated during the sampling process, affecting the purity of the sample. Therefore, the present invention provides a crystallization kettle material sampling device and process. Summary of the Invention

When the circumferential directions of the arc-shaped strip plate 2 and the fan-shaped strip plate 2 are the same, the two form a complete annular plate, and the limiting wheel is provided with an arc-shaped slide groove that cooperates with the fan-shaped strip plate 2.

[0007] Furthermore, a fan-shaped strip plate 1 is fixedly installed on the annular rotating frame, and a lower scraping push plate is slidably installed on the annular rotating frame. An arc-shaped strip plate 1 is fixedly installed on the end of the lower scraping push plate. When the two ends of the arc-shaped strip plate 1 are fully engaged with the fan-shaped strip plate 1, the two form a complete annular plate, and the upper end of the scraping slide is provided with an arc-shaped sliding groove that cooperates with the fan-shaped strip plate 1.

[0013] A sampling process using a crystallization kettle material sampling device comprises the following steps.

[0014] Step 1: Drive the annular rotating rack to rotate so that the transfer square cylinder moves to the bottom of the scraping slide corresponding to the sampling position, and drive the annular slide to rotate so that the sample storage square cylinder without the sample stored in it moves to the bottom of the transfer square cylinder. At this time, the arc strip one is engaged with the limiting slide groove corresponding to the scraping slide, and the arc strip two is engaged with the limiting wheel corresponding to the scraping slide.

[0016] Step three: Drive the scraping rotary plate to rotate, and the end of the scraping rotary plate contacts the inner side of the fan-shaped groove of the scraping slide. Under the action of the scraping rotary plate, the crystals in the fan-shaped groove of the scraping slide fall into the sample storage square tube below. After the scraping rotary plate rotates to disengage from the scraping slide, the scraping rotary plate returns to its initial position, and the scraping slide returns to its initial position, and the replacement slider returns to its initial position synchronously.

[0017] Step 4: Drive the transmission slide to move downward. Under the action of the two magnets, the scraping slide moves downward synchronously.

(3) The present invention can sample multiple positions of the reactor by providing a sampling component, thereby ensuring the comprehensiveness of the sampling. (4) The present invention realizes the process of automatically sampling, transferring and storing crystals from the crystallization reactor by cooperating with the sampling component, the transfer component and the auxiliary component, thereby reducing manual intervention, improving sampling efficiency, and effectively preventing cross contamination from affecting the purity of the sample.

[0035] Example: Reference Figures 1-14 A crystallization kettle material sampling device includes a reactor 101, a sampling assembly is provided on the reactor 101, and the sampling assembly includes a plurality of sampling support seats 111. The sampling support seats 111 are fixedly installed in a circumferential array on the reactor 101. The sampling support seats 111 are rotatably mounted with fan-shaped rotating plates 122. The fan-shaped rotating plates 122 are movably connected to the reactor 101. When the end face of the fan-shaped rotating plate 122 is located at the position closest to the axis of the reactor 101, the end face of the fan-shaped rotating plate 122 and the reverse side are aligned. The inner circumferential surface of the reactor 101 is coplanar, and a scraping slide 112 is slidably installed on the sampling support seat 111. The scraping slide 112 is provided with a fan-shaped groove that cooperates with the fan-shaped rotating plate 122. The scraping slide 112 is used to scrape the crystals on the end face of the fan-shaped rotating plate 122. When the end face of the fan-shaped rotating plate 122 moves to the position farthest from the axis of the reactor 101, the end face of the fan-shaped rotating plate 122 and the end face of the sampling support seat 111 farthest from the axis of the reactor 101 are coplanar.

[0036] The reactor 101 is also fixedly mounted with a plurality of gear boxes 114 in a circumferential array. The gear boxes 114 contain two bevel gears, which mesh with each other to form a gear pair. A limiting wheel 115 is fixedly mounted on the input end of the gear box 114, and the output end of the gear box 114 is fixedly connected to the corresponding fan-shaped rotating plate 122. An annular rotating frame 102 is rotatably mounted on the reactor 101, and a transposition gear ring 104 is fixedly mounted on the annular rotating frame 102. A transposition motor 109 is fixedly mounted on the reactor 101, and a transposition gear 110 is fixedly mounted on the output shaft of the transposition motor 109. The transposition gear 110 and the transposition gear ring 104 mesh with each other to form a gear pair.

[0037] A fan-shaped strip plate 2 127 is fixedly mounted on the annular rotating frame 102, and an arc-shaped strip plate 2 132 is also rotatably mounted on the annular rotating frame 102. A sampling motor 133 is fixedly mounted on the annular rotating frame 102, and the output shaft of the sampling motor 133 is fixedly connected to the arc-shaped strip plate 2 132. When the circumferential directions of the arc-shaped strip plate 2 132 and the fan-shaped strip plate 2 127 are the same, the two form a complete annular plate, and the limiting wheel 115 is provided with an arc-shaped slide groove that cooperates with the fan-shaped strip plate 2 127.

[0038] In the initial position, both ends of the arc-shaped strip 2 132 are fully engaged with the fan-shaped strip 2 127 respectively. At this time, the circumferential directions of the arc-shaped strip 2 132 and the fan-shaped strip 2 127 are the same, and the limiting wheels 115 are in an engaged state with the fan-shaped strip 2 127. Under the action of the fan-shaped strip 2 127, the limiting wheels 115 cannot rotate freely at this time, and then under the action of the gear box 114, the fan-shaped rotating plate 122 cannot rotate freely.

[0039] Start the transposition motor 109 to drive the transposition gear 110 to rotate. Under the action of the transposition gear ring 104, the annular rotating frame 102 rotates synchronously, that is, the sector strip 2 127 and the arc strip 2 132 rotate synchronously. When the arc slots on the limiting wheel 115 corresponding to the arc strip 2 132 and the sector rotating plate 122 to be moved are engaged, the axis of the arc strip 2 132 and the axis of the limiting wheel 115 are in the same straight line. Then start the sampling motor 133 to drive the arc strip 2 132 to rotate, and the limiting wheel 115 rotates synchronously. Then, under the action of the gear box 114, the sector rotating plate 122 rotates, and finally the sector rotating plate 122 rotates 180 degrees.

[0040] A fan-shaped strip 126 is also fixedly installed on the annular rotating frame 102, and a lower scraping push plate 128 is slidably installed on the annular rotating frame 102. An arc strip 131 is fixedly installed on the end of the lower scraping push plate 128. When the two ends of the arc strip 131 are fully engaged with the fan-shaped strip 126, the two form a complete ring plate. The upper end of the scraping slide 112 is provided with an arc-shaped slide groove that cooperates with the fan-shaped strip 126. A lower scraping rod 129 is rotatably installed on the annular rotating frame 102. The lower scraping rod 129 and the lower scraping push plate 128 form a spiral pair. A lower scraping motor 130 is fixedly installed on the annular rotating frame 102, and the output shaft of the lower scraping motor 130 is fixedly connected to the lower scraping rod 129.

[0041] In the initial position, the lower scraper push plate 128 is located at the position closest to the lower scraper motor 130. At this time, the arc-shaped strip 131 and the fan-shaped strip 126 are connected to form a complete ring plate, and the limiting grooves 113 on the scraper slide 112 are connected to the fan-shaped strip 126. Under the action of the limiting grooves 113 and the fan-shaped strip 126, the scraper slide 112 cannot move up and down.

[0042] When the second arc strip 132 is engaged with the limiting wheel 115 corresponding to the required adjustment sector rotating plate 122, the first arc strip 131 is engaged with the limiting slot 113 corresponding to the sector rotating plate 122. After the second arc strip 132 completes the position adjustment of the required sector rotating plate 122, that is, after the sector rotating plate 122 is rotated 180 degrees, the end face of the sector rotating plate 122 and the end face of the sampling support 111 farthest from the axis of the reactor 101 are coplanar. Start the lower scraping motor 130 to drive the lower scraping rod 129 to rotate, so that the lower scraping push plate 128 moves downward. Under the action of the limiting slide groove 113 and the arc strip 131, the scraping slide 112 corresponding to the fan-shaped rotating plate 122 moves downward synchronously. The fan-shaped groove on the scraping slide 112 scrapes off the crystals attached to the end surface of the fan-shaped rotating plate 122, and the crystals scraped off the fan-shaped rotating plate 122 are located inside the fan-shaped groove of the scraping slide 112.

[0043] The reactor 101 is provided with a transfer assembly, which includes a transfer square cylinder 117, which is fixedly mounted on the annular rotary frame 102, and a scraping rotary plate 119 is rotatably mounted on the transfer square cylinder 117. The scraping rotary plate 119 is used to scrape out the crystals in the fan-shaped groove on the scraping slide 112, and a replacement slider 118 is slidably mounted on the scraping rotary plate 119. A reset slider 121 is fixedly mounted on the outer side of the replacement slider 118, and a spring is provided between the reset slider 121 and the annular rotary frame 102. The replacement slider 118 is used to coincide with the projection of the replacement slider 118 and the scraping slide 112 relative to the lower surface of the reactor 101 when the replacement slider 118 is located directly below the scraping slide 112. An internal scraping motor 135 is fixedly mounted on the side of the transfer square cylinder 117, and the output shaft of the internal scraping motor 135 is fixedly connected to the scraping rotary plate 119.

[0044] When the transfer cylinder 117 moves to the bottom of the scraping slide 112 corresponding to the fan-shaped rotating plate 122 to be adjusted, the replacement slider 118 is located under the scraping slide 112, driving the scraping slide 112 to move downward, and the replacement slider 118 moves downward synchronously, and the spring between the reset slide 121 and the annular rotating frame 102 is stretched, finally making the fan-shaped groove on the scraping slide 112 located inside the transfer cylinder 117, and at this time the center line of the rotation connection between the scraping rotating plate 119 and the transfer cylinder 117 and the axis of the fan-shaped groove on the scraping slide 112 are in the same straight line, and then the inner scraping motor 135 is started to drive the scraping rotating plate 119 to rotate, that is, the scraping rotating plate 119 is rotated to the inner side of the fan-shaped groove on the scraping slide 112, and under the action of the scraping rotating plate 119, the crystals accumulated in the fan-shaped groove on the scraping slide 112 are pushed out.

[0045] A scraping slide 120 is also slidably installed on the inner side of the transfer cylinder 117. The surface of the scraping slide 120 closest to the filling slider 118 and the surface of the filling slider 118 closest to the scraping slide 120 are coplanar. The scraping slide 120 is used to clean the residue on the inner side of the transfer cylinder 117 and the scraping turn plate 119. A transmission slide 123 is also slidably installed on the transfer cylinder 117. Magnets 136 are fixedly provided on the transmission slide 123 and the scraping slide 120. The two magnets 136 are arranged opposite to each other and do not contact each other. The magnetic attraction between the two magnets 136 makes the scraping slide 120 move synchronously when the transmission slide 123 moves. A cleaning screw 124 is rotatably installed on the transfer cylinder 117. A cleaning motor 125 is also fixedly installed on the transfer cylinder 117. The output shaft of the cleaning motor 125 is fixedly connected to the cleaning screw 124, and the cleaning screw 124 and the transmission slide 123 form a spiral pair.

[0046] In the initial position, the transmission slide 123 is located at the position closest to the cleaning motor 125, that is, the scraping slide 120 is located at the top of the transfer cylinder 117, and the scraping turn plate 119 is in a vertically upward state. At this time, the surface of the scraping slide 120 closest to the axis of the reactor 101 and the surface of the scraping turn plate 119 farthest from the axis of the reactor 101 are coplanar.

[0047] After the scraping rotary plate 119 pushes out the crystals in the fan-shaped chute on the scraping slide 112, the scraping rotary plate 119 returns to the initial position, and the scraping slide 112 returns to the initial position. At this time, the replacement slider 118 returns to the initial position synchronously, and then the cleaning motor 125 is started to drive the cleaning screw 124 to rotate, so that the transmission slide 123 moves downward. Under the action of the two magnets 136, the scraping slide 120 moves downward synchronously, and the scraping slide 120 pushes downward the crystals remaining on the inner side of the transfer cylinder 117 and the crystals attached to the scraping rotary plate 119.

[0048] The reactor 101 is also provided with an auxiliary component, which includes an annular slide 103. An auxiliary gear ring 105 is rotatably installed on the reactor 101, and the annular slide 103 is slidably installed on the auxiliary gear ring 105. An auxiliary motor 108 is also fixedly installed on the annular rotary frame 102. An auxiliary gear 107 is fixedly installed on the output shaft of the auxiliary motor 108. The auxiliary gear 107 and the auxiliary gear ring 105 are engaged to form a gear pair. The annular slide 103 is slidably installed on the auxiliary gear ring 105. An auxiliary electric cylinder 134 is fixedly installed on the auxiliary gear ring 105. The piston rod end of the auxiliary electric cylinder 134 is fixedly connected to the annular slide 103. A plurality of sample storage square cylinders 106 are movably provided on the annular slide 103, and the sample storage square cylinders 106 are used to store samples.

[0049] The lower end surface of the transfer square cylinder 117 and the upper surface of the auxiliary gear ring 105 are on the same plane. A plurality of T-shaped positioning blocks 116 are fixedly arranged in a circumferential array on the annular slide 103. The lower surface of the sample storage square cylinder 106 is provided with grooves that cooperate with the T-shaped positioning blocks 116. The installation and positioning of the sample storage square cylinder 106 are achieved by the T-shaped positioning blocks 116. The auxiliary gear ring 105 is also provided with a plurality of openings that cooperate with the sample storage square cylinder 106 in a circumferential array. The size of the opening on the auxiliary gear ring 105 is equal to the size of the opening of the sample storage square cylinder 106.

[0050] The auxiliary electric cylinder 134 is activated to move the annular slide 103 away from the auxiliary gear ring 105, that is, the upper surface of the sample storage cylinder 106 is separated from and contacts the corresponding opening on the auxiliary gear ring 105, so that the sample storage cylinder 106 can be easily removed from the annular slide 103. When installing the sample storage cylinder 106 on the annular slide 103, the groove on the lower surface of the sample storage cylinder 106 is engaged with the T-shaped positioning block 116, and then the auxiliary electric cylinder 134 is activated to move the annular slide 103 upward. That is, the upper surface of the sample storage cylinder 106 and the lower surface of the auxiliary gear ring 105 are engaged. At this time, the opening of the sample storage cylinder 106 and the corresponding opening position on the auxiliary gear ring 105 are engaged, and the auxiliary motor 108 is started to drive the auxiliary gear 107 to rotate, so that the auxiliary gear ring 105 rotates, the annular slide 103 rotates synchronously, and the sample storage cylinder 106 on the annular slide 103 also rotates synchronously, so that the required sample storage cylinder 106 can be moved to the bottom of the transfer cylinder 117.

[0051] When the sample storage cylinder 106 is located directly below the transfer cylinder 117, when the scraping slide 120 pushes the crystals in the transfer cylinder 117 downward, the crystals enter the transfer cylinder 117 along the opening on the auxiliary gear ring 105, thus realizing sampling of the crystallization kettle.

[0052] Working principle: Start the transposition motor 109 to drive the annular rotating frame 102 to rotate, so that the transfer square cylinder 117 moves to the bottom of the scraping slide 112 corresponding to the sampling position, and then start the auxiliary motor 108 to drive the annular slide 103 to rotate, so that the sample storage square cylinder 106 without the sample is moved to the bottom of the transfer square cylinder 117.

[0053] At this time, the arc-shaped strip plate 2 132 is engaged with the corresponding limiting wheel 115, and the arc-shaped strip plate 1 131 is engaged with the corresponding limiting slide groove 113. Then, the sampling motor 133 is started first to drive the fan-shaped rotating plate 122 to rotate 180 degrees, and then the lower scraping motor 130 is started to drive the scraping slide 112 to move downward, scraping the crystals attached to the end surface of the fan-shaped rotating plate 122 into the inner side of the fan-shaped groove of the scraping slide 112.

[0054] During the downward movement of the scraping slide 112, the positioning slide 118 moves downward synchronously, and finally the fan-shaped groove of the scraping slide 112 is located inside the transfer square cylinder 117, and the fan-shaped groove of the scraping slide 112 corresponds to the position of the scraping rotary plate 119, and then the auxiliary electric cylinder 134 is started to drive the scraping rotary plate 119 to rotate. Under the action of the scraping rotary plate 119, the crystals in the fan-shaped groove of the scraping slide 112 are pushed downward, and the crystals fall into the sample storage square cylinder 106 below, and then the scraping slide 112 and the scraping rotary plate 119 return to their initial state. Position, then start the cleaning motor 125 to drive the scraping slide 120 to move downward, so that the crystals remaining on the transfer square cylinder 117 and the scraping turn plate 119 are pushed into the sample storage square cylinder 106. At this time, the lower surface of the scraping slide 120 and the upper surface of the auxiliary gear ring 105 are on the same plane, and then start the auxiliary motor 108 to drive the auxiliary gear ring 105 to rotate, and the sample storage square cylinder 106 rotates synchronously, and the auxiliary gear ring 105 completely scrapes the crystals on the lower surface of the scraping slide 120 into the sample storage square cylinder 106, thereby completing the sampling of this position of the crystallization kettle.

[0055] By repeating the above steps, the crystals at the positions of the multiple fan-shaped rotating plates 122 on the crystallization kettle can be sampled.

[0056] The invention also discloses a sampling process using the crystallization kettle material sampling device, which comprises the following steps.

[0057] Step 1: Drive the annular rotating frame 102 to rotate so that the transfer square cylinder 117 moves to the bottom of the scraping slide 112 corresponding to the sampling position, and drive the annular slide 103 to rotate so that the sample storage square cylinder 106 without the sample stored therein moves to the bottom of the transfer square cylinder 117. At this time, the arc strip 131 and the limiting slide groove 113 corresponding to the scraping slide 112 are engaged, and the arc strip 2 132 and the limiting wheel 115 corresponding to the scraping slide 112 are engaged. Then drive the arc strip 2 132 to rotate, and the limiting wheel 115 corresponding to the scraping slide 112 rotates synchronously. Under the action of the gear box 114, the fan-shaped rotating plate 122 is finally rotated 180 degrees. At this time, the end face position of the fan-shaped rotating plate 122 is located on the inner side of the fan-shaped groove of the scraping slide 112.

[0058] Step 2: Drive the lower scraper push plate 128 to move downward, and the arc strip 131 and the scraping slide 112 move downward synchronously. Under the action of the scraping slide 112, the replacement slider 118 moves downward synchronously, and the spring between the reset slide 121 and the annular rotary frame 102 is compressed. The scraping slide 112 scrapes off the crystals on the end face of the fan-shaped rotating plate 122, and the scraped crystals fall into the fan-shaped groove of the scraping slide 112, and finally the fan-shaped groove of the scraping slide 112 is completely located inside the transfer square cylinder 117, and the center line of the rotation connection between the scraping rotary plate 119 and the transfer square cylinder 117 is on the same straight line as the axis of the fan-shaped groove of the scraping slide 112.

[0059] Step three: Drive the scraping rotary plate 119 to rotate, and the end of the scraping rotary plate 119 contacts the inner side of the fan-shaped groove of the scraping slide 112. Under the action of the scraping rotary plate 119, the crystals in the fan-shaped groove of the scraping slide 112 fall into the sample storage square tube 106 below. After the scraping rotary plate 119 rotates to disengage from the scraping slide 112, the scraping rotary plate 119 returns to its initial position, and the scraping slide 112 returns to its initial position, and the replacement slider 118 returns to its initial position synchronously.

[0060] Step 4: Drive the transmission slide 123 to move downward. Under the action of the two magnets 136, the scraping slide 120 moves downward synchronously. The scraping slide 120 pushes the crystals remaining inside the transfer square cylinder 117 into the sample storage square cylinder 106 below, thus completing the sampling of the reactor 101 at this position.

[0061] The present invention is not limited to the above-mentioned specific implementation methods. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work are all within the scope of protection of the present invention.
